This one may not guide your life so much but it’s good to keep in mind. I mean, yeah, we’ve got a few dozen kilometers of rock beneath us at some points but after that, it just gets hotter and hotter until it’s liquid rocks, which is most of the core of this earth. We’re on a driverless spaceship, ladies and gentlemen, fueled from above by a strong flashlight and from below by a furnace. We make nice ovals around the sun but that sun is making ovals in the galaxy and that galaxy is moving in ways that I no longer remember. Again, maybe this won’t change how you go about your life this week but who knows, maybe it’ll shift your perspective a bit.
